Sandra (Ona Grauer) is the main villainess from Lifetime's 2016 film, I Didn't Kill My Sister (airdate May 14, 2016)
15 years prior to the film's events, Sandra was interviewed by anchorman Mason Campbell, when her husband mysteriously died in an a car accident. Since then, Sandra and Mason began an illicit affair, leading to Mason filing for divorce from his wife, fellow news reporter Carmen Campbell, who was about to fire Sandra as her lawyer. Sandra wanted desperately to become Mason's wife, even dragging Mason into her plot to kill Carmen and tamper with her will so they would inherit her fortune.
The film's opening shows Carmen's death, which has Carmen passing out after drinking wine that had been drugged by Sandra, who then dragged the unconscious Carmen into her pool to drown. As part of the plot, Sandra and Mason planned to frame Carmen's sister, Heather (the main protagonist) for the murder, but once Heather was getting close to the truth, the evil Sandra broke into Carmen's home and killed Heather's lawyer, Wayne Hamilton; doing so by bludgeoning Wayne with a trophy.
The plan leads to Heather becoming a suspect, but once Sandra and Mason met up once again, Sandra suggests to Mason that they should kill Heather, which Mason is reluctant to do. Unbeknownst to them, Heather caught the duo together on video, and she went on TV and outed their scheme and affair. Sandra and Mason catch Heather backstage, leading to Sandra attempting to kill Heather with a pair of scissors. When the police arrive, Sandra attempts to claim self-defense, but since her schemes and evil behavior have already been exposed, her claim falls on deaf ears, and to add insult to injury for Sandra, Mason doesn't speak to verify Sandra's claim, knowing full well that they have failed to get away with their crimes, and the villainous duo are arrested to be sent to prison and convicted of their evil deeds.
